Related question re white BMW

Still waiting for the VIN. Going to see it on the 11th.

Has anyone ever seen the krausers that were made for the 78 Motorsport for sThis bike comes with Black bags but to complete the look - in my opinion - the white bags would be stunning. Are they just black bags resprayed white or made white through and through?

There were simply white and black bags available. Nothing specifically made for the Motorsport. They are white plastic, not painted.

As reference my 81 rt had the oil cooler with the enclosed fairing front grill, I put the shark grill on it and removed the oil cooler.

Lots of people blamed the more enclosed grill for diode board failures, but the problem was poorly made diode boards.

In addition, while the Nikasil cylinders were fabulous and light years better than the earlier iron cylinders, they did dump lots of heat to the rider. Many "shade tree engineers" felt adding the bar-type grill would address the heat problem. If it did it was hardly measurable. One sees lots of these bikes running no lowers at all for the same reason.

Looking at the red stripe, I think someone confused the terms "Motorsport" with "Rennsport" edition. It looks to me that the bike could be an attempted upgrade to "Motorsport", however, not exactly that.
The term "Rennsport" was used by BMW in the late 50s early 60s for the race bikes with the towershaft valve drive.
There is always the possibility that certain specials were made for certain markets.
One example is the elusive R100S "Motorsport" for the U.S. that was made for Butler & Smith.

Mike - What does lend a smidgen of credibility to the possibility of "Rennsport" is that according to the "Original BMW Air-Cooled Boxer Twins 1950-1996" book, they produced 30 Rennsport editions in 1992 for the R100RS. Each one had a numbered plaque. That model was the two tone blue and silver style. But nowhere does anyone list a Rennsport in the 80s, and certainly not one with the racing stripe down the tank and to the seat as a riff on the Motorsport style from 1978... I've resigned myself that this is just a cool custom paint job and not a factory special edition. But waiting for the VIN anyhow... - mark

That really is the bottom line. At every rally is see several beautifully done customs, some just paint but others that are Frankenbeemers assembled with love by skillful Airheads. I like them as much as some Factory Specials in original fit and fiddle condition.

it's great to hear that about the appreciation for the custom enhancements. Most of my vintage vehicle experience comes from the old Volvo groupies. (I have an '71 1800e Volvo - a la 'The Saint' - which incidentally he also rode an R100RS as his motorcycle of choice) The resale market and value of the Volvos are all about the original color, accessories, authenticity of the modifications etc. Good to see the spirit amongst the airhead community is appreciation for the bike as art-form rather than slavish recreation of originality.

yeah, but for resale- that same rule ALWAYS applies, regardless of brand. aftermarket goodies are worth (very few) pennies on the $ in terms of resale.

As lkchris says, the subject bike's VIN says it is a 1981 Model Year R100RS produced for the US market that was manufactured in September 1980. The "Australian version of the bike that was a Rennsport edition that was upgraded from 70(71?) to 77hp" claim does not seem to fit with the information from the decoded VIN - nice bike though.

Vin numbers

The current standard for VIN numbers didn't start until around 1983 or 84. I had an '81 RT that was titled (new) as an '81. When I tried toget a new title in another state they insisted it was a 1980 (this was in the early 90's). The DMV didn't care what the original title said, they went according to the VIN and the VIN was a 1980 model. I had to write to BMW and get an official letter to get the state to correct the title.
